The greatest advantage of United States in world war II was its ability to rapidly transition from peace to war and mass produce weapons and war equipment at a colossal scale. This was so effective that the USA was able to make up for time lost, and the nation was able to effectively train the necessary forces and then exert a massive material superiority.
America was able to build up an air force that came to dominate the skies, and with this air superiority, it was all but over for the enemy, the Axis forces.
The effect of all people in China using the same coins and the same writing system was that the trade became much easier.
Answer: Option B
<u>Explanation:
</u>
Communication is the soul of trade and commerce. The usage of a common writing system in China allowed traders and merchants from across the country to understand the nuances of trade and communicate with each other without much problem, no matter which part of the country the traders came from.
The ease of doing business dispensed by a common writing system allowed the contemporary markets to prosper and grow big enough to attract traders and merchants from all over the world.
Having a common system of coins acted like conventionally accepted currency and made day-to-day business much easier. The value of the coins being predetermined, no problems arose in their exchange of products and services.
Isaac Newton was creative in his use of prisms to show how white light is actually made up of multiple colors. He used logic in the way he presented his arguments rhetorically in order to convince readers of the correctness of his conclusions.
Newton was not the first to experiment with passing light through prisms to determine how light works. French philosopher Rene Descartes had done prism experiments of his own. But Descartes had thought that passing through a prism actually modified the light in order to produce the color spectrum. Newton correctly understood that when light refracted through the prism, it revealed the range of colors that were naturally in the light. He then used a second prism, blocking all but one color, to show that a single color passing through a prism was not modified in color. He also showed--by positioning the second prism differently--how the multiple colors of light could be recombined into white light again.
Newton's 1672 paper on light refracting through prisms established his reputation as a scientist. He continued to study light throughout his scientific career, publishing a larger work in 1704 on <em>Opticks </em>(as they spelled "optics" then).
